This work proposes a complete sensor-independent visual system that provides robust target motion detection. First the way sensors obtain images in terms of resolution distribution and pixel neighbourhood is studied. This allows a spatial analysis of motion to be carried out. Then a novel background maintenance approach for robust target motion detection is implemented. Two different situations are considered: a fixed camera observing a constant background where objects are moving and a still camera observing objects in movement within a dynamic background. This distinction lies on developing a surveillance mechanism without the constraint of observing a scene free of foreground elements for several seconds when a reliable initial background model is obtained as that situation cannot be guaranteed when a robotic system works in an unknown environment. Other problems are also addressed to successfully deal with changes in illumination and the distinction between foreground and background elements.
